If you are referring to the Turbo Prepaid VISA Card, you should have received it in 5-10 business days after you were approved for it.
If you didn't receive yours, you need to phone the Card's customer service and report it: (888) 285-4169.
If you filed 6 weeks ago, has the IRS released your refund yet?
If you efiled, double-check with this tool to be sure the return was efiled successfully and accepted:

If that showed it was accepted (or if you mailed the return), what do you see at the IRS website below for the status of your Federal refund?
https://www.irs.gov/Refunds
If that IRS tool shows that the refund has been sent, report back for more info.
If the IRS tool says it is still "being processed", and if it's been longer than 21 days, we can tell you how to speak to a live agent at the IRS to see if they can tell you anything about the delay of your refund.
